8 Claims.

, This invention relates to a singeing apparatus for cloth, and thelike, and mor particularly to an article of this class having improvedradiation facilities for preventing over-heating during continued use.

It is an object of this invention to provide a burner having anopen-sided combustion chamher in which the singeing flame is adapted toburn and over which cloth to be singed is adapted to pass, incombination with a water jacket disposed adjacent the chamber sidewallsfor radiating the excess heat from the burner.

It is another object of this invention to provide an improved singeingapparatus of th class described having a water cooled pipe for holdingthe moving cloth in spaced relation to the burner during a singeingoperation. The water cooled pipes are usually placed in close proximityto the burner, yet a sufficient distance therefrom to hold the fabric inthe proper position. By having means for circulating Water through theburner jacket and through the cloth guiding pipe, overheating of theapparatus is prevented because the steam therein will serve to modifythe heat.

Heretofore singeing burners have given much trouble in warping, due toimproper cooling. Burners have heretofore been provided having a waterjacket on each side, but this has not prevented warping of the burner.By our improved construction, in which the entire periphery of theburner is evenly cooled, warping has been prevented.

Some of the objects of the invention havin been stated, other objectswill appear as the description proceeds when taken in connection withthe accompanying drawing in which:

Figure 1 is an isometric view of an improved singeing apparatus;

Figure 2 is an enlarged transverse vertical sectional view taken alongthe line 2-2 in Figure 1;

Figure 3 is a vertical longitudinal sectional view, with the centralportion thereof broken away, and taken along the line 33 in Figure 1.

Referring more particularly to the drawing, the numeral l denotes a gasfue1 supply pipe having a cap H which closes one end thereof, said pipehaving a longitudinally extending grill l2 in the top side thereof. Thisgrill is adapted to fit in a slot of appropriate size in the pipe Illand to be fixed in position by any suitable means such as welding, apress fit, or the like. It can be seen by observing Figures 1 and 2 thatthe grill I2 has perforations therein for dividing the escaping gas asit flows from the pipe I0.

Extending radially from the pipe H1 and from the opposed edges of thegrill l2 are plates l5. These plates extend on an upward incline asumcient distance to form the sidewalls of a U- shaped combustionchamber I6 in which a flame I1 is adapted to burn, said chamber havingan open upper side over which passes a piece of material to be signedsuch as a fabric l8. Plates l5 are secured to the pipe 10 at the opposededges of the grate [2 by means of weld beads l9; however, it is to beunderstood that other suitable securing means may be employed withoutdeparting from the spirit of the invention (Figure 2).

The pipe II! has disposed therearound and in spaced relation to itsouter periphery, a second pipe 20, said second pipe having an elongatedslot in its upper side, and the edges of this slot are secured to theupper outer edges of plate members I5 by any suitable means such as Weldbeads 2|. Suitable plates 25 are welded to each end of the members l5and 2D and to the plates 25 to close the annular space 23 and to makethis space water-tight. After the pipe 20 has been secured in positionby weld seams 2|, there is provided an annular compartment 23 formedaround fuel supply pipe H) in which a suitable radiation fluid such aswater 24 is adapted to be circulated during the operation of the device.Water is conducted into annular spac 23 and through the space during theoperation of the singeing apparatus by way of an inlet pipe 21. Thisfluid flows into the lower portion of the compartment and around the gaspipe Ill, and then to the other end of the burner assembly where it isexpelled by way of pipes 28 leading from each side of outer pipe 20.Pipes 28 extend downwardly and then inwardly to a T 28a, from which another pipe 29 leads. Connected to pipe 29 as at 290. is an invertedU-shaped pipe 30, through which the radiation liquid passes from thesingeing unit. It will be noted that the U-shaped pipe 30 extendupwardly above the top of the burner unit so that during normaloperation, the liquid will be present in the compartment 23 even ifthere is insuflicient Water pressure to cause the fluid to flow, untilit is converted into steam. When the operator discovers steam issuing,the machine can be stopped before the burner is damaged.

In order to hold the cloth l8 in spaced relation to the burner l2 andalso in spaced relation to the top edges of inclined plates l5, suitablepipes 3| and 32 are provided, said pipes being positioned on each sideof the edges of the burner mouth and substantially parallel to thelongitudinal axis thereof. The pipes 3| and 32 are supported by plates25 and are connected together by a short pipe 36. In actual operationthe water enters a pipe 31 and then passes through pipe 3| into pipe 36and then through pipe 32. From the pipe 32, the water passes into aninverted U-shaped pipe 38. The loop in pipe 38 serves the samepurpose asthe loop=in pipe 30, namely, to normally maintain a supply of waterwithin the pipes 3| and 32 when there is lnsufiicient pressure to causethe water to flow.

In other words, the U-shaped pipes 30 and :38

serve as stops to prevent water from flowing out of the system bygravity.

The flow of water through pipes 21 and 31*is controlled by any suitablemeans such as hand valves 4| and 42 respectively. Althoughthe city watersupply may be employed as a means ior causing, a liquid to flow throughthe pipes-21 and 31, we have shown an independent unit comprising a pump43 driven by motor 44. The pump draws fluid from any suitable sourceintopump 43 by way of an inlet pipe 45 and then ,expels the fluid by Way ofa pipe 46 to forcethe same into'the pipes3l, 32,.and compartment 23.

Attention is called to the fact that forsake of clear disclosurethe-strip of clothmaterial l8, whichtravels overthe burner unit, doesnot extend the entire length of the burner. In operation the entirewidth of the. burner'is usually covered, however, in the presentinstance, the width of the material has been diminished in order to showthe structural features of the apparatus. g

In the drawing and specification, there has been set forth a preferredembodiment of the invention and although specific terms=are employed,they are used in a generic and descriptive sense only and notforpurposes of limitation, the scope of the invention being defined in theclaims.
